Augmented Reality and Data Physicalization
Our work with augmented reality (AR) and physicalization blends a dynamic layer of digital content with physical visualizations. Data physicalizations are a detailed, tangible way to visualize data which engage both the visual and tactile senses. Physicalizations allow us to use the knowledge and context of the real world to interpret data, and allow for collaboration between stakeholders in a visualization. However, since physicalizations are constrained by the physical world, these data representations are often static.
We add interactivity to physicalizations through the use of computer graphics, augmented reality headsets, high-accuracy tracking systems, and custom touch input devices. These technologies provide a means of displaying and interacting with diverse types of data. For instance, in the left figure, ocean currents from the MPAS-O1 climate dataset are shown in AR on top of a physical printout of the ocean depth data. The physical model is tracked, allowing users to move it around and observe how the currents behave based on the ocean depth.
